METHOD OF MAKING SWEATBANDS.

This invention relates to sweatbands and to a method for making the same. More particularly, my invention relates to a sweatband for caps which are only partially attached to the band and merely adjacent the visor thereof, coming incontact with the forehead of the wearer.

Where I have attempted to attach a partial sweatband to a cap, at points merely adjacent the visor thereof, I have found that best results and snugness are obtained by shaping the fabric from which the sweatband is made to conform to the spherical shape of the human head, I have found that I can impart'this spherical contour to the sweatband of the character described by forming an edge of the sweatband of superimposed layers connected, preferably adhesively, of different linear length to obtain, 1n a simple manner, permanent shaping. Thus, where I make a sweatband of leather, I may book or fold the edge thereof, shaping the edge portion in relation to the body port on so that the desirable head curvature may be permanently imparted to the sweatband.

here I have attempted to form a booked edge on the sweatband by an edge turning machine, for quantity production work, I have found that not only does the usual edge turning machine give superimposed layers objectionable in sewing the swea-tband to the hat or cap but the fabric, particularly leather or the like, is so flattened by the edging machine as to destroy the entire function of the booked edge. 7

It is an object, therefore, of my invention to provide a sweatband of the character associated with caps and attached to only that portion of the cap band adjacent the visor, having a booked edge and so disposed from the body thereof as to facilely permit attach; ment by sewing to the band of the hat and so formed that it will assume the shape of the head of the wearer when so fixed in position.

Still more particularly, it is contemplated by my invent-ion to provide a sweatband blank which may be fed through a folding or booking machine whereby the configuration of the edges of the blank will serve, when drawn through the booking or folding machine, to be simultaneously booked and shaped to the desirable contour, at the same time providing a stitching portion which may serve to be attached to the band of the cap by stitching or sewing.

It is a further object of my invention to provide a method for making a sweatband to shape the same to the contour of the head and simultaneously form a booking edge serving to retain the sweatband in the desired shape, the booked edge being so positioned as not to interfere with the sewing or stitching necessary to assemble the sweatband and cap.

In its more particular embodiment, my in- Vention has for an object thereof the provision of a sweat-band of the type which isatta-ched to the hat band for a portion thereof adjacent the visor and one which is so formed as to conform with the shape of the head of the wearer and which. will retain this shape after attachment to the ca It is contemplated by my invention to provide a blank for making'a sweatband which is susceptible of quantity production and a method for simultaneously booking and shaping the same.

To attain these objects and such further objects as appear herein or may be hereinafter pointed out, I make reference to the accompanying drawing forming a part hereof, in whic Figure 1 'is a plan. view of a sweatband blank;

Figure 2 is a plan view of a completely formed sweatband;

Figure 3 is a perspective view of the same;

Figure 4 is a diagrammatic view, in side elevation, showing a sweatband in the process of construction;

Figure 5 is a plan view of the same;

Figure 6 is a sectional view taken longitudinally of the booked edge of the sweatband as shown in Figure 3.

It will be observed that my invention, in its preferred form, comprises a sweatband made from a thin sheet of fabric, such as leather, whose body portion 10 is provided with a booked edge 11. Where the sweat-band is to be used with a cap and attached to the band thereof for a portion adjacent the visor thereof, it is preferred that the sweatbanzl comprise a strip having curved edges 11 and 12, the edge 12 being of a curvature which, when formed to the general configuration of the head, will coincide with the plane surface across the section of the head. The edge 12 so curved as to gracefully terminate with the ends of the sweatband and give suflicient contacting surface at the middle portion. Though a strip as shown in Figure 2, provided with a booked edge 11, gives: sufficient rigidity to the sweatband when attached to the hat, I may utilize the booked ed e 11 not only to stiffen the edge of thefsweaband but to make the entire sweatband more nearly conform to the spherical contour of the head. For this purpose I provide a blank as shown in Figure 1 with the curved edges 10 and 11 pointed at its ends 13 and 14, with the curvature of 10 less than 11*, the curved portion 10 being so calculated as to lie in a plane surface when the blank is curved and positioned in a hat band. The curve formed by the arcuate edge 11 is broken at 155 and 14 by an oblique cut, for purposes which will appear hereafter. This blank is preferably die-stamped in a manner as will be readily understood.

For forming a booked edge of this blank and prior thereto I apply along the arcuate edge 11 an adhesive layer as shown at 15. This may be a rubber cement which becomes aggressive by pressure applications to a similarly curved surface. I may then form the booked edge by folding over the edge strip 11 inwardly along the dotted line 16. The application ofpressure will serve to hold this folded portion in position. Folding over the edge 11 in the plane surface will form undesirable kinks or beads and be further objectionable in that it holds the strip in the hatband so that it does not conform to the shape of the head.

To give the self-sustaining spherical contour to the strip I therefore peen the strip along the booked edge 1.1,thereby actually increasing the length of the inwardly turned strip 11 so that when adhesively held in position it will retain the strip in the form shown in Figure 3, conforming more nearly to the spherical. contour of the head. It will be observed that the oblique lines 13 and 14 may be continued along the natural curve of the edge 11 and still obtain the desirable effects above outlined whereby a permanently shaped, as well as booked, edged sweatband is obtained. For purposes of quantity produc tion, I will now describe the utility of forming the blank with the obliquely cut edges 13 and 145.

In Figure 4 I have diagrammatically illustrated an edge folding or booking apparatus comprising a table 17 having an edge turning cam 18 disposed in front of a rotatable mushroom shaper or peener 19 disposed in front of the rolls 20 and 21. A blank shown in Figure 1, having the adhesive 15 applied thereto, is fed through the apparatus de scribed. The strip 10 is fed from right to left and is made to first engage the edge turning cam 18 by an arcuate sweep given to the strip by the operator in a direction parallel to the edge to be folded. The edge 11 is immediatelpicked up by the peener 19, beginning from the very tip, such'as 13, and is gradually bent over or folded from a point ad acent the tip intermediate the ends of the oblique cut portion and as shown in the drawing, since the tip is a sharp point, the turning down will be effective from a point intermediate the ends of the oblique cut 13 at approximately the point where the dotted line 16 merges into the oblique cut portions 13 and '14; It will be observed that the cut 13 being oblique, the peener 19 will gradually turn down the edge and with the revolution of the peener, proper- 1y timed, an elongation will be given to the turned edge 11 necessary for obtaining the spherical contour previously described. Final contacting action to adhesively attach the folded edge 11 in position is iven to it by the pressure rolls 20 and 21. t will be observed that the speed of the rolls 20 and 21 to take u the work in reference to the peener 19 is sue as to retain the spherical contour, as more clearly shown in Figure 4, as the work leaves the rolls 20 and 21.

In Figure 6 I have shown a section through an edge strip 11 with the portion 11 properly peened in position, serving to retain the general spherical configuration of the sweat band. I attribute the proper formation of the booked edge tending to retain the spherical contour of the sweatband to the gradual manner in which the inclined edges 13 and 13 feed the strip to and away from the peener, thus obtaining an application of pressure of'the peener tending to produce a smooth and uncrimped effect of the booked edge, the work bein picked up from a single layer to a doub e layer in gradually increasing amounts.

Furthermore, I do not require any further preparation of the sweatband as it leaves the peener and rolls to properly attach the same to the band of a cap.

It will thus be observed that I have provided a novel sweatband having proper form retaining characteristics, as well as the provision of a blank for making the same, which will permit of its construction by quantity 7 constituting a body portion and edge portion adapted to form therewith a. booked edge and including the ends of said edge portion obliquely out, With a layer of pressure aggressive adhesive along the length of the edge portion, feeding the blank in a direction par allel to the edge to be folded, gradually folding said edge,beginninginterinediatetheends of the oblique out portion and progressively folding a flap upon the body portion of the 10 blank along the edge, pressing said edge into engaging position and peening said folded edge from one end of the blank to the other.

In Witness whereof I have hereunto signed my name this 1st day of November, 1928.
